feat: redact unknown paths by default in chiware StatMiddleware

[saurav-malani]

Description

StatMiddleware, by default will now use for unmatched paths the value /redacted in the reqType tag. This can guarantee that captured stats don't introduce a tag cardinality issue. This default behaviour can be overridden through the RedactUnknownPaths option.
